Definitions

  • the invention relates to a continuously variable transmission with at least two gear members and at least one connecting member, which the gear members operatively connected to each other and is arranged in its position continuously displaceable relative to the gear members according to the preamble of claim 1.
  • a conical friction ring gear is made of GB-PS 298 676 known.
  • a guide member is guided parallel to the axes of the conical friction wheels on a guide axis, which guides the friction ring along the conical friction wheels.
  • the continuously variable transmission may be provided with at least two gear members and at least one connecting member which operatively interconnects the gear members and is continuously displaceable in position relative to the gear members, wherein the link is disposed in a guide means pivotally mounted about an axis of rotation is whose axis direction comprises a component which is arranged parallel to a plane spanned by the two axes of the gear members plane.
  • the connecting member for example by means of a displaceable holder, moves translationally relative to the gear members when the guide means is pivoted about the axis of rotation.
  • the connecting member translationally displaced in a first direction or in a second direction, which is opposite to the first direction.
  • the translational movement in this case only be caused by the rotation of the two gear members, so that only forces have to be applied separately for the pivoting movement about the axis of rotation, while those for the displacement or translational movement In itself required forces are provided by the gear train itself or by the rotation of the two gear members and the connecting member.
  • guide means is understood herein to mean a structure in which the connecting member is rotatably mounted. Also, the connecting member by means of the guide device relative to the gear members also translationally displaced.
  • the present continuously variable transmission is designed to be particularly small.
  • the mechanical position detection or the mechanical position signal can determine and forward exact data even under structurally difficult operating conditions.
  • the mechanical position signal possible to dispense with electronic components and / or optical components directly in the field of gear members or the connecting member.
  • according to the invention can be dispensed with electronic or optical components in the immediate vicinity of the gear members, so that there prevailing high temperatures and the presence of a traction fluid does not adversely affect the position detection described here.
  • the position determination is constructed very susceptible to interference, so that a particularly reliable and reliable position determination is guaranteed.
  • the object of the invention is also achieved by a continuously variable transmission with at least two gear members and at least one connecting member, the gear members operatively connected to each other and is arranged in its position continuously displaceable relative to the gear members, in which the continuously variable transmission has a position detection, with which the relative position of the connecting member relative to at least one transmission member at a gear stoppage can be determined.
  • position detection are information about the position of the link even at a gear stoppage or at a motor standstill at any time.
  • the determination of the position of the connecting member is advantageously possible independently of the operating state of the respective continuously variable transmission.
  • the position of a connecting member with respect to at least one transmission element even with an occurring slip between the individual To determine limbs particularly accurate, since the present mechanical position detection or the present mechanical position signal can detect and transmit the position regardless of a rotation speed determination.
  • the present invention is particularly suitable for use with a conventional bevel ring gearbox, in which a torque is transmitted, for example, from an input cone via a rotating friction ring to an output cone, or vice versa.
  • the term “mechanical position signal” describes any components which are suitable for mechanically transmitting the position of the connecting member from a first region to a second region.
  • first region preferably means that region of the continuously variable transmission in which the transmission members or the connecting member are arranged directly.
  • second area in the context of the invention comprises either a region of the continuously variable transmission which is different from the first region or an area which is arranged completely outside the continuously variable transmission. In any case, the first and the second area substantially differ by the respective prevailing thermal conditions, which are very different in particular during the operation of the continuously variable transmission in the respective first or second region.
  • a variant embodiment provides that the mechanical position signal is connected to data acquisition and / or data processing means. This ensures that the information that provides the mechanical position signal depending on the friction setting, safely and effectively detected and processed. It has been found that such data acquisition and / or data processing means can be realized particularly economically by standardized optical and / or electronic components.
  • a variant provides that the partition is a housing wall of the continuously variable transmission. This makes it possible to carry gear data particularly reliable to data acquisition and / or data processing means.
  • the partition is a fluid space wall of the continuously variable transmission. This ensures that the mechanical position signal, for example, in a traction fluid filled fluid space determined reliable and can be reliably transmitted from this fluid space.
  • a mechanical position signal by a partition be it by a fluid space wall or by a housing wall of the continuously variable transmission structurally particularly easy to implement, since the implementation of a mechanical position signal by such walls of the prior art already well controlled is.
  • a mechanical position signal only moderately high demands on constructive solutions in connection with a continuously variable transmission.
  • a particularly preferred embodiment provides that a translational position signal is converted into a rotational position signal.
  • the mechanical position signal can be integrated in a space-saving manner in a continuously variable transmission. Since such conversion mechanisms of the prior art are well known, a mechanism of such a mechanical position signal can be transmitted particularly reliably.
  • the continuously displaceable connecting member has a guide device which is mounted on a rotation axis and the rotation axis has a rotational position signal.
